Help!! problem about capacitance and inductance...
please help me...
god bless u all...
1.) A capacitance of 2.0 microFarad with an initial charge Qo is switched into a series circuit consisting of a 10.0 ohms resistance.
Find Qo if the energy dissipated in the resistance is 3.6 mJoules.
2.) An inductance of 4.0 milliHenries has a voltage
V= ( 2.0e^ (10^ (3t) ) (v). Obtain the maximum stored energy. When will the current be zero??

1) When is the energy dissipated measured? RC circuits discharge with a specific rate.
2) Inductances have energy stored in the magnetic field in accordance with 1/2 L i^2, where i is current. Because current and voltage are 90 degrees out of phase (pure L circuit), it is not possible to go further with this problem.
